Malaysia seeks 'important person' in Nam murder

National police chief Khalid Abu Bakar said Sunday that the new suspects are in addition to the seven North Koreans already being sought in last month's poisoning death of Kim Jong Nam at Kuala Lumpur's airport.

The young North Korean leader declared "that the whole world will soon witness what eventful significance the great victory won today carries", the report said, declaring Saturday as the "March 18 revolution" because of the "great leaping forward" in North Korea's rocket industry.

North Korea has conducted five nuclear tests and a series of missile launches.

"We do not want to interfere in (other country's) political matters, but it is our responsibility to investigate a murder case which occurred within our jurisdiction".

Malaysian police have previously identified eight North Koreans wanted for questioning in connection with the killing of Kim Jong Nam, some of them hiding in the North Korean embassy. However, the regime has reportedly refused to scale down its missiles tests.

One clue as to whether the North has made strides in its engine capability can be found in one of the eight photos published on the Rodong's front page on Sunday, which shows the engine flame.

They said judging by the flame and duration of the burn, the latest engine could carry a rocket or missile over 5,500 kilometers.

The UN believes North Korea is using its so-called space programme to design a missile capable of hitting the US. Tillerson was in Beijing Saturday meeting with his Chinese counterpart, Wang Yi, to discuss a range of issues such as cooperation between the world's two biggest economies to curb the North's nuclear ambitions. "We hope all parties, including our friends from the United States, could size up the situation in a cool-headed and comprehensive fashion and arrive at a wise decision".

Juche refers to North Korea's homegrown ideology of self-reliance. "China has done little to help!"

The rocket engine test comes as U.S. Secretary of State Rex Tillerson is in Asia, with observers saying the trip aims to put further pressure on Pyongyang to give up its nuclear and long-range missile programs.

During his visit to Seoul, Tillerson admitted that Washington's "strategic patience" policy toward Pyongyang was over.
